Hi MedEvil,
These are my physical devices.
When I checked with PCI/PnP Audio, there is a device driver installed as "nVIDIA HDMI @nVIDIA MCP73 - High Definition Audio Controller"
Finally, I checked with DirectX Diagnostic, it showed there is no sound card driver installed. And Windows Audio Service is disabled. Do I need to enabled Windows Audio Service?
I don't think I need to enabled that service for Audio but I'm not sure.
I'll try to solve this later. Because it is not a right place to discuss the issue
![:cheers:](http://reboot.pro/public/style_emoticons/default/cheers.gif)
and I'll make a new topic in Windows 7 forum.
I'm using Vista Drivers instead.
Comparing vistaPE, 7PE can't accept any PNF file, while booting, if there is one PNF file is there, loading process will suddenly stop with error popup.
Thanks for your help.
B Regards,
